Reaction Steps

A mixture of glutaronitrile (5.00 g, 53.13 mmol) and thiosemicarbazide (9.68 g, 106.26 mmol) in TFA (50 mL) was heated at 85° C. for 4 h. The reaction was cooled to room temperature and poured into a mixture of ice and water. Sodium hydroxide pellets were added to the mixture until it was basic (pH 14). The white precipitate was collected by suction filtration, rinsed with water and dried to provide 5,5′-(propane-1,3-diyl)-bis(1,3,4-thiadiazol-2-amine) (1004, 13.72 g). 1H NMR (300 MHz, DMSO-d6) δ 7.06-7.03 (s, 4H), 2.87 (t, J=7.5 Hz, 4H), 2.02-1.95 (m, 2H).
